Track India's NavIC (IRNSS) navigation constellation live. NavIC is ISRO's own satellite navigation system — India's answer to GPS — providing positioning accuracy better than 20 metres across India and 1,500 km beyond its borders.
See real-time positions of the NavIC satellites in geosynchronous and geostationary orbit, propagated from public orbital data, together with how many of them are above your horizon right now and how good the resulting position geometry is.
NavIC's standalone positioning service is currently unavailable. A receiver needs signals from at least four satellites to solve for position, and only three are operational for navigation — IRNSS-1B, IRNSS-1I and NVS-01. Six first-generation satellites (IRNSS-1A, 1C, 1D, 1E, 1F and 1G) remain in orbit but suffered rubidium atomic clock failures and are limited to short-message service, IRNSS-1H never reached its orbit in 2017, and NVS-02 has been stranded in a transfer orbit since January 2025 after the pyro valve for its orbit-raising engine failed to fire. The NavIC timing service still works, which is why the outage is largely invisible to phone users — devices fall back to GPS, Galileo and BeiDou. NVS-03 is scheduled to launch on GSLV-F18 in a 15 to 20 October 2026 window and will restore the fourth working satellite; see the NVS-03 launch tracker.
NavIC was designed as a seven-satellite system: three in geostationary orbit at fixed longitudes over the equator, and four in geosynchronous orbit inclined at 29 degrees, which trace a figure-eight ground track over India each day. Replacement satellites and the second-generation NVS series have been added since, so the number of IRNSS and NVS objects actually in orbit is higher than seven and changes as ISRO launches replacements. The constellation roster on this page is read from the live orbital catalog rather than a fixed number. Being in orbit is not the same as broadcasting a healthy navigation signal — IRNSS-1A remains in orbit but lost its atomic clocks.
The coverage panel shows how many NavIC satellites are above your horizon right now, where each one sits in the sky by elevation and compass bearing, and the resulting dilution of precision — HDOP, VDOP, PDOP and GDOP. DOP is a multiplier rather than an error: with an HDOP of 1.5, one metre of ranging error becomes about 1.5 metres of horizontal position error. Satellites spread widely across the sky give a low DOP; satellites bunched together give a high one even when every signal is perfect.
NavIC's primary service area covers the entire Indian subcontinent and extends 1,500 km beyond India's borders, including Sri Lanka, Bangladesh, Nepal, Bhutan, the Maldives, parts of Pakistan, Afghanistan and Myanmar, plus the Indian Ocean, the Bay of Bengal and the Arabian Sea. Because the satellites are geostationary and geosynchronous, coverage over India is continuous rather than made up of passes.
GPS is a global system of 31 satellites in medium Earth orbit at 20,200 km. NavIC is regional, in GEO and GSO orbits at 35,786 km, designed for India and its surroundings. NavIC's dual-frequency L5 and S-band design corrects for ionospheric delay automatically — the main source of GPS error at India's equatorial latitudes — and its satellites sit higher in the sky over India, which helps in urban areas. The second-generation NVS-01 added the L1 band used by GPS, Galileo and BeiDou, making NavIC compatible with standard smartphone chipsets.
